The trio of The Stammer takes on gloom, and repurposes it in a calming framework. Brian Brotman’s pseudo-spoken singing style captures an air of relatable honesty, which are paired with bass lines that pull you through the street and fresh snapping percussion that becomes formidable. Tonight, with a new space-patrolling synth song “Gone” in hand, the group heads to Kung Fu Necktie. Relative newcomers Blood Sound, whose combination of throbbing bass, airy synth, stabilizing percussion and spoken, reflective vocals that create danceable darkwave, are also on bill. The percussion propelling airy pop-rock of New York’s Graniero brothers, Caravela, wraps up the evening. Kung Fu Necktie, 1250 N. Front St., 8pm, $6, 21+ – Michael Colavita
